Q:What are metric tubes and British tubes? What's the difference between them? How do you choose flanges?
It should be the metric tube and the British tube, that is to say, the B series and the A series.According to the flange diameter of the steel pipe, the flange diameter should be chosen according to the outer diameter of the steel pipe.The national standard flanges sold on the market are generally B series, and the A series shall be noted.My company website has flange standard, and corresponding steel pipe size. If necessary, please: Hebei, Mengcun Hao elbow elbow pipe manufacturers, station search,
Q:Mechanical flange problems,
The 6 holes of M12 are evenly distributed on one flange, the drilling depth of the screw hole is 24mm, and the depth of the wire tapping is 23mm.
Q:How to calculate the flange quote formula?
According to the round steel process, the forging blank blanking, workshop workers. These three aspects of the impact, there is no point in the foundation is difficult, it is best to calculate the flange finished weight, price, and then calculated according to flange finished weight flange price.
Q:Hole is a through hole on the flange surface?
Flanges in the narrow senseFlange (Flange), also called flange or flange plate. The flange is the part that connects the pipe to the pipe and is connected to the end of the pipe.
Q:PROE flat sheet metal design whole wall and the flange wall what is the difference?
but if not a lot of this piece of sheet metal bending, and the shape is not Affirmative square, with it is necessary to cut the flange murals one or several features.
Q:Flange SO40-2.
Now the method is SO 40-25 M.Refer to HG/T20592-2009 steel pipe flanges (PN Series)
Q:What's the difference between a clip flange and a flange?
This problem, mainly refers to the butterfly valve in two forms, pairs of clamp and flange type:The clip butterfly valve (valve itself without flange) is a double headed bolt to connect the valve between the two pipe flanges. The clip butterfly valve is simple, small and light in weight and consists of only a few components. The utility model can be rapidly opened and closed only by rotating 90 DEG, the operation is simple, and the valve has good fluid control characteristics.
Q:Flanges of different sizes
Variable diameter flange, also known as Reducing Flange, and its inner diameter and the standard flange diameter, there are some differences.In engineering, when the standard flange can not match the fittings and pipes, the reducing flange is used.China's national standards flange standard (GB) and chemical industry standard (HG) two categories, the new chemical industry standard HG/T20592 ~ 206352009 flange is used to the EN as the representative of the European standard pipe flanges (nominal pressure expressed by PN) and the United States as the representative of the American ASME system (nominal pipe flange the pressure expressed by Class), between them the nominal size of the feature size is different; moreover, our country pipeline diameter series is also divided and metric Inch series series, there are differences in the nominal size; in addition, when there are special requirements, such as flange instrument joints, when the glass lined the characteristics of some special requirements (give it a separate "glass lining of different diameter flange" HG/T2140-2009 standard). Therefore, the inevitable mixing in the project, the use of reducing the flange diameter of the method is the simplest and most effective solution, thus the emergence of non-standard variable flange.
Q:Which flange is the front pipe case flange and the cylinder flange?
The front pipe case flange is the tube part, which is connected with the tube plate.A cylinder flange is a flange that is connected with a shell on the shell side, and no flange is used on the ordinary heat exchanger.
Q:About the difference between valve flanges RTJ, RF
Different pressure flange thickness is different, they use the bolt is also different. Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. Any connecting parts that are bolted and closed in the vicinity of the two planes are generally referred to as flanges, such as the connections of the ventilation ducts, which can be called flanges". However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges". Reducer flange for motor and reducer connection, as well as reducer and other equipment between the connection. The flange has a good overall performance, it is widely used in chemical industry, construction, water supply, drainage, oil, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power, aerospace, shipbuilding and other infrastructure projects. Three, RTJ and RF, RTJ and RF, respectively, indicate the form of the flange sealing surface: RTJ means that the metal ring is sealed and used in high pressure situations, such as RTJ, the maximum pressure is 42.0MPa. RF indicates bursting seal, for low pressure applications such as RF, maximum pressure 15.0MPa.
